To all whom it may concern:

Be it known that I, AUoUs'r HILD'r, a citi zen of the United States,residing at Jersey City, in the county of Hudson and State of NewJersey, have invented certain new and useful Improvements inQuilting-Machines and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and tocharacters of reference marked-thereon, which form a part of thisspecification.

This invention relates, generally, to that class of sewing machinesknown in the art as quilting machines; and the present invention hasreference, more particularly, to a novel quilting machine for quiltingfabrics of the various kinds, in which are employed in connection withsuitable driving and operating mechanism, a plurality of reciprocatingneedles and a plurality of correspondingly disposed rotary hooks orloopers, all arranged in such a manner and cooperating with one another,so that the fabric or goods may be provided with suitablequilt-stitchings.

The presentinvention has for its principal object to provide amultiple-stitching quilting machine embodying, primarily, the featuresherein-above stated in a simple operative and effective manner; and, theinvention has for its further purpose to provide in connection with aquilting machine, a bracket-like hook or looper-carrying element, whichis slidably disposed upon the bed-plate or frame of the sewing machine,so that the said element, when it is desired to remove a rotary hook orlooper, can be easily and quickly moved in a rearward direction awayfrom beneath the quilted portion of the fabric or goods, so that thelatter will not act as an obstruction, and that the sewing machineoperator may readily get at the hook or lo-oper, for removal from itssupport, as will hereinafter more fully appear.

The invention has for its further object to provide in connection with aplurality of sewing needles, arranged in rows, a plurality of suchbracket-like elements, each of which is capable of independent rearwardmovement for the purpose above stated, and a battery of correspondinglylocated rotary hooks or loopers, adapted to be variously located uponthe bed-plate or frame of the sewing machine, so as to produce variousquiltstitchings.

Other objects of the present invention not at this time moreparticularly enumerated will be clearly understood from the followingdetailed descriptionof the present invention.

With the various objects of the present invention in view, the saidinvention consists, primarily, in the novel quilting machine hereinafterset forth; and, the invention consists, furthermore in the novelarrangements and combinations of the several devices and parts, as wellas in the details of the construction of the said parts, all of whichwill be more fully described in the following specification, and thenfinally embodied in the clauses of the claims which are attached to andform an essential part of the said specification.

The invention is clearly illustrated in the accompanying drawings, inwhich Figure 1 is a front face view of the various devices and elementsembodying the principles of the present invention, certain parts of thesewing-machine proper being omitted from said view as nonessential to aclear understanding of the said invention.

Fig.- 2 is a plan or top view of a fragmentary portion of the bed-plateor frame of the sewing machine, said view illustrating in connectiontherewith, a pair of reciprocatory needle-bars and needles mountedthereon and suspended from said bars, and an arrangement of the slidablydisposed hook or looper-supporting bracketdike elements, with the rotaryhooks or loopers in position, show- 1 g one embodiment of the principlesof the present invention; and Fig. 3 is a vertical sectionalrepresentation taken on line 3-3 in said Fig. 2, looking in thedirection of the arrow a2, said view showing in connection therewith, insection, a portion of the upper part of the machine-frame; also inelevation a fragmentary portion of the fabric sewed upon, and of abearing, a rod movable in said bearing, upon which the needle-bar ismounted, and means for actuating said rod.

Fig. 4 is a detail transverse section, taken on line in said Fig. 2,looking in the direction of the arrow y; and Fig. 5 is a detailtransverse sectional representation of tion of the spindle with which itis connected, showing one means ofoperatively connectmg the said hooksor loopers and spindle.

' Figs. 6 and 7 are plan or top views of two other arrangements ofrotary hook or loopersupporting bracket-like elements, and moditiedarrangements of hooks. or loopers, said views showing two otherembodiments of and 3, indicates a portion of a suitable overhang orupper frame-work forming a portion of the main frame of the quiltingmachine. The said bed-plate 1 and the said frame-portion or overhang 2may be of any suitable lengths, according to the size of the material tobequilted, and the consequent number of sewing needles and correspondingrotary hooks or loopers and bobbins necessarily employed. I

Suitably secured to the said frame-portion or overhang 2, by means ofbolts 3, or

otherwise, is a bracketmember or element, as 4, provided with forwardlyprojecting bearing-portions 5,.of any suitable construction in which isslidably'mounted a rod or stem, as 6. The said bracket-member or ele-,

ment 4 is also provided, at a suitable point, with anotherrforwardly'projecting bearing n 7 in which is rotatably mounted a shaft 8. Anotherportion of this shaft is also mounted in a suitably disposedbearingmember or portion, as 10, of the frame-portion 9. of theframe-work of the machine, other bearing-members'or portions 11 and 12being also provided in connection with this portion of themachine-frame. Rotatably mounted'insaid bearing-members or portions 11and 12 is a vertical spindle 13 carrying a miter or bevel-wheel 14, uponits the variousnliter or upper portion, which is in mesh with a miter orbevel-wheel 15 mounted upon the above-mentioned shaft or spindle 8,while upon its lower portion the said spindle 13 isjprovided withanother miter or bevelwheel 16. Suitably mounted, in suitable locations,upon the said bed-plate 1, are bearing-members, as 17, in which isrotatably mounted a main driving shaft 18 upon which is secured a miterorbevel-gear 19 which meshes with the miter or bevel-gear '16, As'willbe evident, from an inspection ,of Fig. 1 of the drawings, the rotarymotion of the said main shaft 18 is thus transferred by means ofthe saidvertical spindle 13, and bevel-gears to the upper shaft 8. Suitablymounted upon the said shaft18. is an eccentric 20, or'other similardevice, the stem 21 of which is suitably connected with a rod or bar 22having a perforated pivot-pin receiving portion, as 23, oscillatorilymounted upon a suitably screwthreaded pivot-pin, as 24. As indicated insaid Fig. 1 of the drawings, the screwrthrea ded, shank of the saidpivot-pin is screwed into a. suitably formed collar 25, which is mountedupon the previously-mentioned rod or stem 6, and has its end in retainedengagement with the said rod or stem 6, substantially as indicated.Thus, by means of this mechanism, the rotary motion of the shaft 8 istransferred to the said rod or stem 6, the latter receiving thereby areciprocatory movement in the bearing-members or portions 5.

Suitably mounted and secured upon the lower end-portion of the rod orstem 6 is a suitably formed cross-bar or plate, as 26, and secured uponthe end-portions 27 and 28 of the said bar of plate 26, by means ofscrews 29, or other suitable fastening means, are suitably formedneedle-bars or elements, as 30 and 31, to which are attached in anysuitable manner, usually by means of fastening screws, as 32, aplurality of sewing needles, as 33 and 34.

Movably disposed between suitably placed guiding members, as 35, securedin position upon the said bed-plate l by means of screws 36, orotherwise, are a plurality of rotary hook or looper andbobbin-supporting bracketlike elements, generally designated by thereference-character 37.

These elements may be arranged in the manner illustrated moreparticularly in Figs. 1, 2 and 3 of the drawings, the general outline ofeach element in that case, when viewed from the top, forming aparallelogram, but the said elements may also be arranged, substantiallyas indicated in Figs. 6 and 7 of the drawings, in which case the outlineof each element, when viewed from the top,.is in the form of aright-angled parallelogram.

Referring now to the said Figs. 1 to 3 inclusive, it will be seen, thateach element 37 comprises a rearwardly extending supporting member 38and an upwardly projecting portion 39, from which extends in a forwarddirection a supporting table or element, as 40. The rearwardly extendingmember 38 is made with an elongated opening, as 41, in which is arrangeda binding screw 42, having its screw-threaded shank screwed into aproperly located screwthreaded hole 43 in the bed-plate 1, asillustrated in Fig. 3 of the drawings. The said binding screw 42 has anannular flange or shoulder 44 for binding purposes, and is also providedwith a head or enlargement, as 45, forming a means for the manipulationof the said screw 42, as will be clearly evident. Upon or near its rearend-portion,

the said rearwardly extending supporting member 38 is also provided witha suitable fingerpiece, as 46, for sliding the element 37 backwardly orforwardly upon the said bedplate 1, in the manner and for the purposeshereinafter more fully set forth.

Any desired number of these rotary hook or looper and bobbin-supportingbracketlike elements 37 may be arranged between a pair of theaccordingly located guiding members 35, as will be clearly evident, andthe supporting members 38 of the respective elements 37, may be properlyconnected in their sliding relation by longitudinally extending ribs ortongues 47 registering with grooves 48, substantially as illustrated inFig. 4 of the drawings. The supporting table or element of each hook orlooper and bobbin-supporting element 37 is provided in its upper surfacewith a suitable recess or depression, as 49, and with a series ofspindle-receiving holes 50, 51 and 52. As an illustration, in Fig. 2 ofthe drawings, I have shown an arrangement of three ele ments 37, placedso as to provide a front row of holes 50, a rear row of holes 52, and anintermediate row of holes 51. Rotatably disposed in each hole is aspindle 53, formed in its upper portion with a receiving socket 54 forthe arrangement therein of the tubular stem 56 of a rotary hook orlooper 55, the parts being secured in their assembled relation by meansof a screw 57 in a manner, as illustrated in Fig. 5 of the drawings. Thestemsor spindles 53 have their lower end-portions projecting from thesaid holes 50, beneath the lower surfaces of the supporting tables orelements 40, and suitably mounted upon the said projecting endportionsof the said stems 53, are pinions 58 and bevel or miter gears 59, thesaid bevel or miter gears 59 being in mesh with correspondingly placedbevel or miter gears 60 which are suitably mounted upon the previouslymentioned main driving shaft 18 substantially as illustrated in Fig. 1of the drawings. When thus assembled, the rotary hooks or loopers 55 aredisposed in the previously mentioned depressions or recesses 49 of thesupporting tables of the respective elements 37, substantially asillustrated in Fig. 3. Rotatably disposed in each hole 51 is a spindle61, said spindles 61 having their upper end-portions projecting into thedepressions or recesses 49 of the respective sup porting tables 40 andbeing retained in operative. relation by means of suitable collars 62,or other suitable retaining means connected with the said spindles 61.The said stems or spindles 61 have their lower endportions projectingfrom the holes 51, beneath the lower surfaces of the supporting tablesor glements 40, and suitably mounted upon the said projectingend-portions of the said stems or spindles 51 are gears, as 63',

which. are in mesh with the pinions or gears 58 of the stems or spindles53. Also rotatably disposed in each hole 52 is a stem or spindle 64, thesaid stems or spindles having mounted upon their upper end-portions, inthe manner of the stems or spindles 53 and the rotary hooks or loopers55, similar hooks or loopers 65. The said stems or spindles 64 havetheir lower end-portions projecting from the said holes 52, beneath thelower surfaces of the supporting tables or elements 40, and suitablymounted upon the said projecting end-portions of the said stems orspindles 64 are gears, as 66, which are in mesh with thepreviously-mentioned gears 63.

It will be fully understood that the rotary motion of each stem orspindle 53 is transmitted by this arrangement of, gears 58, 63 and 66 tothe stem or spindle 64, so that the rotation of all the hooks orloopers, when the quilting machine is being operated, will be in thesame direction.

Of course, it must be understood, that 'within each rotary hook orlooper casing is the usual bobbin-shell or casing 67, see Fig. 5, inwhich the thread-bobbin is placed.

The material which is to be quilted is indicated by thereference-character 6S, and the same is passed upon and above the upperface of the supporting table or element 40, the needles 33 and 34passing into and through the material or fabric 68, during the sewingoperation, causing the threads of the said needles to pick up and loopwith the threads from the bobbin contained in the rotary hooks orloopers, while the quilted material passes in a rearward direction,usually between suitably located feed-rolls, as 69 and 70, to a pointbeyond the machine. The reference-character 71 indicates a suitablyformed presser-bar or plate, provided with holes or perforations 72through which the needles pass, the said presser-bar or plate beingsuitably mounted upon the lower end of a rod or stem 73 and beingadapted to reciprocate in suitable guide-holes, as 74, in thebearing-members 5. A sleeve or collar 75 is secured at the properlocation upon this rod or stem 73, said sleeve or collar 75 beingprovided with a finger or projection 76 with which a suitablecam-device, as 77, mounted upon the shaft or spindle 8, is adapted to bebrought into operative engagement for intermittently raising andlowering the said presser-bar or plate 71, as will be clearly evident.

As has been previously stated, any desired number of sewing needles maybe employed, using with the bed-plate 1 of the sewing machine acorresponding number of hook or looper and bobbin-carrying bracket-likeelements 37, which according to the kind of lei ' the table, in a mannerrepresented in Fig. 2 of the drawings, or they may be arranged at rightangles to the said front edge of the sewing table, as represented inFigs. 6 and 7 of the drawings.

hooks or loopers, as 78, 79, and 81, and

their corresponding bobbins may be employed, the hooks or loopers beingrotated in the same direction by means of the gears 82, 83, 84, 85, 86,87 and 88; or, as indicated in Fig. 7, a staggered or zig-zagarrangement of hooks or loopers, as 89, 90, 91 and 92 may be made, thehooks or loopers being rotated in the same direction by means of thegears 93, 94, 95, 96, 97, 9s and 99.

Of course it will be understood that with these arrangements of therotary hooks or loopers and the various driving gears, as represented insaid Figs. 6 and 7, the means for actuating the driving mechanism ischanged accordingly, and a corresponding number of needle-bars andneedles must be arranged accordingly.

From the foregoing description of the present invention it will beclearly evident, that I have provided a novel and simplyeonstructedquilting machine in which a plurality of reciprocating sewing needlesare employed with cooperating rotary hooks or loopers and theirthread-bobbins; and, furthermore, by the rearward sliding arrangement ofany one of the bracket-like elements 37, in case of the breaking of athread, or placing of a new thread-bobbin in the bobbin-shell, thebracket-like element can easily be moved clear of the fabric or material68,so as to permit of the thread being rearranged, orthe placing of anew thread- .bobbin in the bobbin-shell, after which the said rearwardlymoved bracket-like element can be slid back into its normal orinitialsewing position and secured in said position.

I am fully aware that changes may be made in the general arrangementsand com binations of the several devices and parts, as well as in thedetails of the construction of the said parts, without departing fromthe scope of the present invention as described in the foregoingspecification, and as defined in the clauses of the claims which areappended thereto.
